Structurally more elaborate acrylates bearing heteroaromatic substituents such as 2-pyridinyl react on very slow rate (<15% conversion after 96 h). Current work aims to overcome these problems. For a discussion on first cycle aminohydroxylation of such substrates, see: Cross-Coupling D. Raatz, C. Innertsberger, O. Reiser, Synlett 1999, 1907.
